Specified by:

accept in interface Expression

getName

public String getName()

getMultipartName

public List<String> getMultipartName()

setName

public void setName(String string)

withName

public Function withName(String name)

setName

public void setName(List<String> string)

isAllColumns

public boolean isAllColumns()

setAllColumns

true if the function is "unique"

Returns:

true if the function is "unique"

setUnique

public void setUnique(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() }"
