Method Detail

getConstrainedColumnList

public List<RolapStar.Column> getConstrainedColumnList()

Description copied from interface: StarPredicate

Returns a list of constrained columns.

Specified by:

getConstrainedColumnList in interface StarPredicate

Returns:

List of constrained columns

getConstrainedColumnBitKey

public BitKey getConstrainedColumnBitKey()

Description copied from interface: StarPredicate

Returns a bitmap of constrained columns to speed up comparison

Specified by:

getConstrainedColumnBitKey in interface StarPredicate

Returns:

bitmap representing all constraining columns.

getChildren

public List<StarPredicate> getChildren()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equalConstraint

public boolean equalConstraint(StarPredicate that)

Description copied from interface: StarPredicate

Returns whether this Predicate has the same constraining effect as the other constraint. This is weaker than Object.equals(Object): it is possible for two different members to constrain the same column in the same way.

Specified by:

equalConstraint in interface StarPredicate

Parameters:

that - Other predicate

Returns:

whether the other predicate is equivalent

minus

public StarPredicate minus(StarPredicate predicate)

Description copied from interface: StarPredicate

Returns the logical inverse of this Predicate. The result is a Predicate which holds whenever this predicate holds but the other does not.

Specified by:

minus in interface StarPredicate

Parameters:

predicate - Predicate

Returns:

Combined predicate

toSql

public void toSql(SqlQuery sqlQuery,
                  StringBuilder buf)

Specified by:

toSql in interface StarPredicate

getOp

protected abstract String getOp()

describe

public void describe(StringBuilder buf)

Description copied from interface: StarPredicate

Appends a description of this predicate to a StringBuilder. For example:

• =any
• =5
• in (2, 4, 6)

Specified by:

describe in interface StarPredicate

Parameters:

buf - Builder to append to

toString

public String toString()

Overrides:

toString in class Object
