appendDebugString

public void appendDebugString(java.lang.StringBuilder s)

Description copied from class: ParseTreeNode

appends a String representation of this node including it's children to the given StringBuilder

Overrides:

appendDebugString in class ParseTreeNode

renderSQL

public void renderSQL(java.lang.StringBuilder s,
                      java.lang.Object[] oqlArgs,
                      java.util.List sqlArgs)

Description copied from class: ParseTreeNode

Renders this node into a StringBuilder as SQL statement, copying arguments from oqlArgs to sqlArgs if needed.

Overrides:

renderSQL in class ParseTreeNode

setTypeFromChildren

public void setTypeFromChildren()

Overrides:

setTypeFromChildren in class ParseTreeNode

getResultClass

public java.lang.Class<?> getResultClass()

Description copied from class: ParseTreeNode

Calculates the resulting Java class of this node, which is used if it is part of the select expression. It will return the default Java class of the current type or java.lang.Object if ParseTreeNode.type is null.

Overrides:
