Method Details

parseTree

public HBaseScanSpec parseTree()

isAllExpressionsConverted

public boolean isAllExpressionsConverted()

visitUnknown

public HBaseScanSpec visitUnknown(LogicalExpression e,
 Void value)
                           throws RuntimeException

Description copied from class: AbstractExprVisitor

Handles implementation-specific expressions not known to the visitor structure. Since there are no "visitFoo" methods for these "unknown" expressions, subclassses should use the functionally-equivalent instanceof approach to parse out these "unknown" expressions.

Specified by:

visitUnknown in interface ExprVisitor<HBaseScanSpec,Void,RuntimeException>

Overrides:

visitUnknown in class AbstractExprVisitor<HBaseScanSpec,Void,RuntimeException>

Throws:

RuntimeException

visitBooleanOperator

public HBaseScanSpec visitBooleanOperator(BooleanOperator op,
 Void value)
                                   throws RuntimeException

Specified by:

visitBooleanOperator in interface ExprVisitor<HBaseScanSpec,Void,RuntimeException>

Overrides:

visitBooleanOperator in class AbstractExprVisitor<HBaseScanSpec,Void,RuntimeException>

Throws:

RuntimeException

visitFunctionCall

public HBaseScanSpec visitFunctionCall(FunctionCall call,
 Void value)
                                throws RuntimeException

Specified by:

visitFunctionCall in interface ExprVisitor<HBaseScanSpec,Void,RuntimeException>

Overrides:

visitFunctionCall in class AbstractExprVisitor<HBaseScanSpec,Void,RuntimeException>

Throws:

RuntimeException
