StringLike Class

public class StringLike

    extends StringOperator
    implements BinaryOperator

A class for representing "like" operator that is operated on the supplied two strings. It accepts two strings firstString and secondString. The evaluation of this operator should return true if ((firstString.toUpperCase()).indexOf( (secondString.toUpperCase())) > -1), otherwise return false.

Method Detail

equals(Object) Method

public boolean equals(Object o)
Override to check the caseInsensitiveMatch flag as well.

Overrides
ComplexExpressionImpl.equals(Object)

getLeftHandSide() Method

public Object getLeftHandSide()
Description copied from BinaryOperator.getLeftHandSide()
Returns left hand side operand of this binary operator.

Returns

The left hand side operand.

getParameterSignature() Method

public Class[] getParameterSignature()
Description copied from Expression.getParameterSignature()
Returns the parameter signature for this Expression. Because the sub-expressions within the Expression are typically arguments or operands, some type validation is performed by examining the class types of the sub-expressions against the Expression's parameter signature.
The tests that are performed are:
1. The number of sub-expressions must equals the number of parameter entries.
2. The class type of any sub-expression (or the result of evaluating the sub-expresssion) must equal the class type of the corresponding parameter entry.
3. Any null parameter entries are ignored and are considered optional sub-expressions.

Returns

the Class array containing the parameter signature.

getRightHandSide() Method

public Object getRightHandSide()
Description copied from BinaryOperator.getRightHandSide()
Returns right hand side operand of this binary operator.

Returns

The left hand side operand.

hashCode() Method

public int hashCode()
Override to check the caseInsensitiveMatch flag as well.

Overrides
ComplexExpressionImpl.hashCode()

isCaseInsensitiveMatch() Method

public boolean isCaseInsensitiveMatch()
