Method Detail

getExpression

public static ExpressionContext getExpression(String expression)

Converts the given string expression into an ExpressionContext.

getExpression

public static ExpressionContext getExpression(Expression thriftExpression)

Converts the given Thrift Expression into an ExpressionContext.

getFunction

public static FunctionContext getFunction(Function thriftFunction)

Converts the given Thrift Function into a FunctionContext.

getFilter

public static FilterContext getFilter(Expression thriftExpression)

Converts the given Thrift Expression into a FilterContext.

NOTE: Currently the query engine only accepts string literals as the right-hand side of the predicate, so we always convert the right-hand side expressions into strings. We also update boolean predicates that are missing an EQUALS filter operator.

getFilter

public static FilterContext getFilter(Function thriftFunction)

getFilter

public static FilterContext getFilter(ExpressionContext filterExpression)

Converts the given filter ExpressionContext into a FilterContext.

NOTE: Currently the query engine only accepts string literals as the right-hand side of the predicate, so we always convert the right-hand side expressions into strings. We also update boolean predicates that are missing an EQUALS filter operator.
