Uses of TypeSignature in org.apache.druid.math.expr

Classes in org.apache.druid.math.expr that implement TypeSignature

Modifier and Type	Class	Description
class	ExpressionType	The type system used to process Druid expressions.

Methods in org.apache.druid.math.expr with parameters of type TypeSignature

Modifier and Type	Method	Description
static ExpressionType	ExpressionType.fromColumnType(TypeSignature<ValueType> valueType)	The expression system does not distinguish between ValueType.FLOAT and ValueType.DOUBLE, so this method will convert ValueType.FLOAT to ExpressionType.DOUBLE.
static ExpressionType	ExpressionType.fromColumnTypeStrict(TypeSignature<ValueType> valueType)	The expression system does not distinguish between ValueType.FLOAT and ValueType.DOUBLE, so, this method will convert ValueType.FLOAT to ExpressionType.DOUBLE.
