Constructor Detail

MethodCallExpr

public MethodCallExpr()

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.

MethodCallExpr

MethodCallExpr(int tokenType,
               java.lang.String tokenName,
               java.lang.Class clazz,
               Expression target,
               Expression[] args)

This constructor is called by specialized nodes. It calls setChildren in order to initialize the node's child expr.

Parameters:

tokenType - the token tpye

tokenName - the name of this node

clazz - the Java type of this node

target - the target expression of this method call

args - the arguments of this method call

Method Detail

clone

protected java.lang.Object clone()
                          throws java.lang.CloneNotSupportedException

Creates and returns a copy of this object.

Overrides:

clone in class NodeImpl

Returns:

the copy

Throws:

java.lang.CloneNotSupportedException - thrown by super.clone()

getTarget

public Expression getTarget()

Returns the target expression of this method call. The target expression can be an instance of ThisExpression or an instance of an arbitrary other Expression, e.g. FieldAccessExpression.

Specified by:

getTarget in interface MethodCallExpression

Returns:

the target expression

getMethodName

public java.lang.String getMethodName()

Returns the method name.

Specified by:

getMethodName in interface MethodCallExpression

Returns:

the method name

getArguments

public Expression[] getArguments()

Returns the argument array of this method call.

Specified by:

getArguments in interface MethodCallExpression

Returns:

the argument array
