Uses of IExpression in isql

Methods in isql that return types with arguments of type IExpression

java.util.Map<java.lang.String,IExpression>

ClausesBuilder.buildSelect(java.util.List<ISQLSelectParser.SelectItem> lstSelect, ColumnValues values, Groups groups) Builds a map alias -> result expression from the select clause.

Uses of IExpression in isql.builder

Methods in isql.builder that return IExpression

IExpression

ExpressionBuilder.buildExpression(ISQLSelectParser.IExpression expression) The main method to extract the expression tree from an ANTLR parsed expression.

Uses of IExpression in isql.expression

Subinterfaces of IExpression in isql.expression

interface	ISimpleExpression the expressions that don't contain an operator
interface	IWhereExpression Expressions that can be used in a where clause (not aggregate functions, not case)

Classes in isql.expression that implement IExpression

class	AggregateFunction function to aggregate rows of the view (for example SUM, AVERAGE...).
class	CaseExpression calculates the result of a CASE-WHEN-THEN expression
class	ColumnExpressionByGroup A simple table-column expression.
class	ColumnExpressionSimple An expression composed by a single column
class	ConstantExpression Expression consiting of just a constant, like a number or a string
class	DoubleExpression The combination of two other expression through a binary operator (e.g.
class	UnaryExpression To evaluate an expression with an unary operator

Methods in isql.expression that return IExpression

IExpression

WhenThen.getThen()

Constructors in isql.expression with parameters of type IExpression

AggregateFunction(IExpression expression, Groups groups, AggregateType aggregateType)

CaseExpression(Column test, IExpression expElse, java.util.List<WhenThen> lstWhenThen)

DoubleExpression(IExpression a, IExpression b, IBinaryScalar operator)

UnaryExpression(IExpression expression, IUnary unary)

WhenThen(When when, IExpression then)

Uses of IExpression in isql.predicate

Methods in isql.predicate with parameters of type IExpression

static WhereView

WhereView.fromExpression(IExpression exp) Builds a view from an expression (the expression contains the involved columns, and therefore the involved tables).

Constructors in isql.predicate with parameters of type IExpression

ComparisonPredicate(IExpression a, IExpression b, IComparison comparison)

InPredicate(IExpression toTest, IConstant[] seqIn, ColumnValues values, boolean negated)

LikePredicate(IExpression test, java.lang.String like, ColumnValues values, boolean negated)
