public final class EndsWithCallExpr

extends MethodCallExpr

implements EndsWithCallExpression

This node represents the method call expression String.endsWith. Children of this node are a target expression (e.g. a FieldAccessExpression) and the method argument which is an arbitrary expression.

Constructor Detail

EndsWithCallExpr

public EndsWithCallExpr()

The noarg constructor is needed for ANTLR support and deserialization. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.

EndsWithCallExpr

public EndsWithCallExpr(antlr.Token token)

The noarg constructor is needed for ANTLR support. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.

EndsWithCallExpr

EndsWithCallExpr(Expression target,
                 Expression[] args)

This constructor is called by the query tree instance. It delegates to the super class constructor.

Parameters:

target - the target expression of this method call

args - the arguments of this method call

Throws:

JDOQueryException - if the result type of target is not a string or the length of args is not equal 1.

EndsWithCallExpr

EndsWithCallExpr(Expression target,
                 Expression arg)

This constructor is called by the query tree instance. It delegates to the super class constructor.

Parameters:

target - the target expression of this method call

arg - the argument of this method call

Method Detail

arrive

public void arrive(NodeVisitor visitor)

Delegates to the argument visitor.

Specified by:

arrive in interface Node

Overrides:

arrive in class NodeImpl

Parameters:

visitor - the node visitor

leave

public java.lang.Object leave(NodeVisitor visitor,
                              java.lang.Object[] results)

Delegates to the argument visitor.

Specified by:

leave in interface Node

Overrides:

leave in class NodeImpl

Parameters:

visitor - the node visitor

results - the result array

Returns:

the object returned by the visitor instance

walkNextChild

public boolean walkNextChild(NodeVisitor visitor,
                             java.lang.Object resultOfPreviousChild,
                             int indexOfNextChild)

Delegates to the argument visitor.

Specified by:

walkNextChild in interface Node

Overrides:

walkNextChild in class NodeImpl

Parameters:

visitor - the node visitor

resultOfPreviousChild - the result computed by leaving the previous child node

indexOfNextChild - the index in the children array of the next child to walk

Returns:

the boolean value returned by the visitor instance
