Type Params Return Type Name and description
public TupleExpression addExpression(Expression e)
public Expression getArguments()
public List<Expression> getExpressions()
public GenericsType[] getGenericsTypes()
public Expression getMethod()
public String getMethodAsString()
This method returns the method name as String if it is no dynamic calculated method name, but a constant.
public MethodNode getMethodTarget()
Returns:
the target as method node if set
public Expression getObjectExpression()
public ASTNode getReceiver()
public String getText()
public boolean isImplicitThis()
Returns:
true if no object expression was specified otherwise if some expression was specified for the object on which to evaluate the method then return false
public boolean isSafe()
Returns:
is this a safe method call, i.e. if true then if the source object is null then this method call will return null rather than throwing a null pointer exception

Method Detail

@Override public TupleExpression addExpression(Expression e)

public Expression getArguments()

@Override public List<Expression> getExpressions()

public GenericsType[] getGenericsTypes()

public Expression getMethod()

public String getMethodAsString()

This method returns the method name as String if it is no dynamic calculated method name, but a constant.

public MethodNode getMethodTarget()

Returns:
the target as method node if set

public Expression getObjectExpression()

public ASTNode getReceiver()

public String getText()

public boolean isImplicitThis()

Returns:
true if no object expression was specified otherwise if some expression was specified for the object on which to evaluate the method then return false

public boolean isSafe()

Returns:
is this a safe method call, i.e. if true then if the source object is null then this method call will return null rather than throwing a null pointer exception

public boolean isSpreadSafe()

public boolean isUsingGenerics()

public void setArguments(Expression arguments)

public void setGenericsTypes(GenericsType[] genericsTypes)

public void setImplicitThis(boolean implicitThis)

public void setMethod(Expression method)

public void setMethodTarget(MethodNode mn)

Parameters:
mn - the target as MethodNode, mn==null means no target
