Method Detail

testNonNull

public boolean testNonNull()

Description copied from interface: TupleDomainFilter

Used to apply is [not] null filters to complex types, e.g. a[1] is null AND a[3] is not null, where a is an array(array(T)).

In these case, the exact values are not known, but it is known whether they are null or not. Furthermore, for some positions only nulls are allowed (a[1] is null), for others only non-nulls (a[3] is not null), and for the rest both are allowed (a[2] and a[N], where N > 3).

testBytes

public boolean testBytes(byte[] buffer,
                         int offset,
                         int length)

Specified by:

testBytes in interface TupleDomainFilter

Overrides:

testBytes in class TupleDomainFilter.AbstractTupleDomainFilter

testLength

public boolean testLength(int length)

Description copied from interface: TupleDomainFilter

Filters like string equality and IN, as well as conditions on cardinality of lists and maps can be at least partly decided by looking at lengths alone. If this is false, then no further checks are needed. If true, eventual filters on the data itself need to be evaluated.

Specified by:

testLength in interface TupleDomainFilter

Overrides:

testLength in class TupleDomainFilter.AbstractTupleDomainFilter

toString

public String toString()

Overrides:

toString in class Object
