public GTLTExpression()

方法详细资料

getType

public int getType()

setType

public void setType(int t)

Type is an integer here for speed purposes, however one of the constants should be used.

参数:

t - The type of expression.

setIgnoreCase

public void setIgnoreCase(boolean v)

isIgnoreCase

public boolean isIgnoreCase()

isTrue

public boolean isTrue(Object o,
                      Query q)
               throws QueryExecutionException

Return whether this expression evaluates to true. The actual comparison is performed by: Utilities.compare(Object,Object) which copes with the object types.

指定者:

isTrue 在类中 Expression

参数:

o - The current object to evaluate the expression on.

q - The Query object.

返回:

true if the expression evaluates to true.

抛出:

QueryExecutionException - If the expression cannot be evaluated.

toString

public String toString()

从类复制的说明: Expression

Return a string representation of the expression, making this abstract forces sub-classes to provide an implementation.

指定者:

toString 在类中 Expression

返回:

A string representation of the expression.
