getExpression

public static ExpressionContext getExpression(Expression thriftExpression)

Converts the given Thrift Expression into an ExpressionContext.

getExpressionFromPQL

public static ExpressionContext getExpressionFromPQL(String pqlExpression)

Converts the given PQL expression into an ExpressionContext.

getExpression

public static ExpressionContext getExpression(AstNode astNode)

Converts the given AstNode into an ExpressionContext.

getFunction

public static FunctionContext getFunction(Function thriftFunction)

Converts the given Thrift Function into a FunctionContext.

getFunction

public static FunctionContext getFunction(FunctionCallAstNode astNode)

Converts the given FunctionCallAstNode 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.

getFilter

public static FilterContext getFilter(ExpressionContext filterExpression)
