ParseTreeNode	getRightOperand()
void	renderSQL(java.lang.StringBuilder s, java.lang.Object[] oqlArgs, java.util.List sqlArgs) Renders this node into a StringBuilder as SQL statement, copying arguments from oqlArgs to sqlArgs if needed.
void	setOwnType() For Array access, sets the type of this node to the array child, so the parent comparison node can correctly set the right sides type in the second pass.

getExpressionResultType

public de.ipcon.db.oql.ExpressionResultType getExpressionResultType()

Overrides:

getExpressionResultType in class ParseTreeNode

getResultClass

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

FIXME 2020-01 ps: only explicitly implemented for Arrays, check default fallback functionality for arbitrary binary expressions.

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

Overrides:

renderSQL in class ParseTreeNode

setOwnType

public void setOwnType()

For Array access, sets the type of this node to the array child, so the parent comparison node can correctly set the right sides type in the second pass.
