Package com.apple.foundationdb.relational.api.fluentsql.expression

Toolbox of expressions used for constructing structured queries.

Interface Summary

Interface	Description
BooleanExpressionTrait	This represents a mixin of logical operations.
ComparableExpressionTrait<P extends DataType,T extends Expression<P>>	This represents a comparable expression.
Expression<T extends DataType>	The super type of all expressions, an expression is typed with a Relational DataType.
ExpressionFactory	A factory that can be used to construct a Expression.
ExpressionFragment<T extends DataType>
Field<T extends DataType>	Represents a (nested) field in a SQL table.
FunctionLike<T extends DataType>	Represents a function.
Literal<J,P extends DataType>	This represents a literal, we assume literal type is ordered which is sufficient for now, but this is not necessarily true, something to think about in the future.
NumericExpressionTrait<N extends DataType.NumericType>	This is a mixin of numerical operations.
ScalarExpression<T extends DataType>	This represents a scalar expression.

Class Summary

Class	Description
BooleanFunction	This represents a boolean function.
BooleanLiteral	This represents a boolean literal.
ComparableFunction<P extends DataType,T extends Expression<P>>	Represents a comparable function.
NestedBooleanExpression	A helper expression for supporting syntactical nesting.
NumericFunction<N extends DataType.NumericType>	This represents a numeric function.
NumericLiteral<N extends java.lang.Number,D extends DataType.NumericType>	This represents a numeric literal.
ParsingFragment<T extends DataType>	This represents an opaque query fragment, this is usually used in two situations.
StringLiteral	This represents a string literal.
UserDefinedField<T extends DataType>	This represents a user-defined field, this allows the user to explicitly set the field name and type without resorting to any form of metadata resolution.
