getVars

public List<Var> getVars()

getExprs

public Map<Var,Expr> getExprs()

forEachExpr

public void forEachExpr(BiConsumer<Var,Expr> action)

Call the action for each (variable, expression) defined. Not called when there is no expression, just a variable. (c.f. forEachVarExpr(java.util.function.BiConsumer<org.apache.jena.sparql.core.Var, org.apache.jena.sparql.expr.Expr>)).

forEachVarExpr

public void forEachVarExpr(BiConsumer<Var,Expr> action)

Call the action for each variable, in order. The expression may be null.

forEachVar

public void forEachVar(Consumer<Var> action)

Call the action for each variable, in order.

contains

public boolean contains(Var var)

hasExpr

public boolean hasExpr(Var var)

getExpr

public Expr getExpr(Var var)

get

public org.apache.jena.graph.Node get(Var var,
 Binding binding,
 FunctionEnv funcEnv)

add

public void add(Var var)

add

public void add(Var var,
 Expr expr)

addAll

public void addAll(VarExprList other)

remove

public void remove(Var var)

update

public void update(Var var,
 Expr newExpr)
