FunctionCallIdentifier

public FunctionCallIdentifier()

FunctionCallIdentifier

public FunctionCallIdentifier(ArrayList<ParameterExpression> paramExpressions)

Method Detail

setFunctionName

public void setFunctionName(String functionName)

sets the function namespace (if specified) and name

Parameters:

functionName - the (optional) namespace information and name of function. If both namespace and name are specified, they are concatenated with "::"

setFunctionNamespace

public void setFunctionNamespace(String passed)

getNamespace

public String getNamespace()

getParamExprs

public ArrayList<ParameterExpression> getParamExprs()

rewriteExpression

public Expression rewriteExpression(String prefix)

Overrides:

rewriteExpression in class DataIdentifier

getOpCode

public Expression.FunctCallOp getOpCode()

validateExpression

public void validateExpression(DMLProgram dmlp,
                               HashMap<String,DataIdentifier> ids,
                               HashMap<String,ConstIdentifier> constVars,
                               boolean conditional)

Validate parse tree : Process ExtBuiltinFunction Expression is an assignment statement NOTE: this does not override the normal validateExpression because it needs to pass dmlp!

Parameters:

dmlp - dml program

ids - map of data identifiers

constVars - map of constant identifiers

conditional - if true, display warning for 'raiseValidateError'; if false, throw LanguageException for 'raiseValidateError'

toString

public String toString()

Overrides:

toString in class DataIdentifier

variablesRead

public VariableSet variablesRead()

Overrides:

variablesRead in class DataIdentifier

variablesUpdated

public VariableSet variablesUpdated()

Overrides:

variablesUpdated in class DataIdentifier

multipleReturns

public boolean multipleReturns()

Description copied from class: DataIdentifier

Method to specify if an expression returns multiple outputs. This method must be overridden by all child classes.

Overrides:

multipleReturns in class DataIdentifier

Returns:

true if expression returns multiple outputs
