Field Detail

### AND_TYPE

    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### COLLECTION_CONTAINS_TYPE

    public static final short COLLECTION_CONTAINS_TYPE

  Deprecated.
  The CollectionContains expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### dateFormat

    public static final DateFormat dateFormat

  Deprecated.
  A date formatter for "MM/dd/yyyy HH:mm:ss z" (02/28/2000 15:58:35 MST).

### defPropertyColumnMap

    public static final Map defPropertyColumnMap

  Deprecated.
  The default map of property name to document table column name.

### defPropertyTypeMap

    public static final Map defPropertyTypeMap

  Deprecated.
  The default map of property names to valid value class.

### docMDTable

    public String docMDTable

  Deprecated.
  The document_metadata table name this should use.

  Set this to null for this to only handle explicit properties. In this case, if a property is found that is not in the `propertyColumnMap`, this will either produce SQL that will never match (if `failOnNonExplicit` is false) or throw an exception (if `failOnNonExplicit` is true).

  See Also:
    `RefDocumentProvider.DOC_MD_TABLE`

### docTable

    public String docTable

  Deprecated.
  The document table name this should use.

  See Also:
    `RefDocumentProvider.DOC_TABLE`

### EQUALS_TYPE

    public static final short EQUALS_TYPE

  Deprecated.
  The Equals expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### failOnNonExplicit

    public boolean failOnNonExplicit

  Deprecated.
  Control what happens if `docMDTable` is null and a property is found that isn't in `propertyColumnMap`.

  If this is true, an exception will be thrown; otherwise, SQL that will never match any document will be generated (default).

### GREATER_OR_EQUALS_TYPE

    public static final short GREATER_OR_EQUALS_TYPE

  Deprecated.
  The GreaterOrEquals expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### GREATER_THAN_TYPE

    public static final short GREATER_THAN_TYPE

  Deprecated.
  The GreaterThan expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### instance

    public static final RefSQLGenerator instance

  Deprecated.
  A default static instance.

  This can be used to access any of the default utility method implementations:

  - `getExpressionType(com.bea.p13n.expression.Expression)`
  - `getExpressionString(short)`
  - `isLegalSingleValueExpressionType(short)`
  - `getSQLOperator(short)`
  - `toSQLLike(java.lang.String, boolean, boolean)`
  Those methods exist as instance methods to allow for subclasses to override behavior.

### LESS_OR_EQUALS_TYPE

    public static final short LESS_OR_EQUALS_TYPE

  Deprecated.
  The LessOrEquals expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### LESS_THAN_TYPE

    public static final short LESS_THAN_TYPE

  Deprecated.
  The LessThan expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### LIKE_TYPE

    public static final short LIKE_TYPE

  Deprecated.
  The StringLike expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### NOT_EQUALS_TYPE

    public static final short NOT_EQUALS_TYPE

  Deprecated.
  The NotEquals expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### NOT_TYPE

    public static final short NOT_TYPE

  Deprecated.
  The LogicalNot expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### OR_TYPE

    public static final short OR_TYPE

  Deprecated.
  The LogicalOr/LogicalMulitOr expression type.

  See Also:
    `getExpressionType(com.bea.p13n.expression.Expression)`, Constant Field Values

### propertyColumnMap

    public Map propertyColumnMap

  Deprecated.
  The map of Criteria property to table column name this should use.

  If the property name from the expression is in this map, then the associated value will be the `document` table column name in the resulting SQL statement. If the property name is not in this map, then it is assumed the property is from the `document_metadata` table (unless `docMDTable` is set null, in which case an exception is raised). For example, if the property name is "identifier" and the associated value in the map is "ID", then all expressions written against "identifier" will get converted into SQL statements againsts the "ID" column of the `document` table.

### propertyTypeMap

    public Map propertyTypeMap

  Deprecated.
  The map of property to valid value class this should use.

  If the property name from the expression is in propertyColumnMap, it also needs to be in this map. The associated value is the Class object minimum type that the literal in the expression being compared to the property must have. For example, if the property name "size" is mapped to the "DOCUMENT_SIZE" column in `propertyColumnMap` and mapped to `Number.class` here, then, in the expression, all comparisions to "size" must be against numbers (e.g. "size != 1024", "size < 10000.0").

### sortExplicitOnly

    public boolean sortExplicitOnly

  Deprecated.
  Control if sorting should happen on explicit properties only.

  Explicit properties are those that are mapped to `document` table columns in `propertyColumnMap`. If the sortBy of a Search contains a non-explicit property reference and `docMDTable` is not null, this will control what happens. If this is false (the default), then the SortCriteria will be assigned to the Info instance and no database level sorting will occur; something else should handle the sorting (the `sort(java.util.List, com.bea.p13n.content.document.ref.RefSQLGenerator.Info)` method can be used to sort a List of DocumentMetadataDefs). If this is true, then the property will be skipped for the sort and all sorting will occur in the database.
