Method Detail

accept

public void accept(ExpressionVisitor expressionVisitor)

Specified by:

accept in interface Expression

getName

public String getName()

setName

public void setName(String string)

isAllColumns

public boolean isAllColumns()

setAllColumns

public void setAllColumns(boolean b)

isIgnoreNulls

public boolean isIgnoreNulls()

setIgnoreNulls

public void setIgnoreNulls(boolean ignoreNulls)

This is at the moment only necessary for AnalyticExpression initialization and not for normal functions. Therefore there is no deparsing for it for normal functions.

Parameters:

ignoreNulls -

isDistinct

public boolean isDistinct()

true if the function is "distinct"

Returns:

true if the function is "distinct"

setDistinct

public void setDistinct(boolean b)

getParameters

public ExpressionList getParameters()

The list of parameters of the function (if any, else null) If the parameter is "*", allColumns is set to true

Returns:

the list of parameters of the function (if any, else null)

setParameters

public void setParameters(ExpressionList list)

getNamedParameters

public NamedExpressionList getNamedParameters()

the parameters might be named parameters, e.g. substring('foobar' from 2 for 3)

Returns:

the list of named parameters of the function (if any, else null)

setNamedParameters

public void setNamedParameters(NamedExpressionList list)

isEscaped

public boolean isEscaped()

Return true if it's in the form "{fn function_body() }"

Returns:

true if it's java-escaped

setEscaped

public void setEscaped(boolean isEscaped)

getAttribute

public Expression getAttribute()

setAttribute

public void setAttribute(Expression attribute)

getAttributeName
