Schema - Class in relop

Each tuple has a schema that defines the logical view of the raw bytes; it describes the types, lengths, offsets, and names of a tuple's fields.

Schema(int) - Constructor for class relop.Schema

Constructs a schema for the given number of fields.

SearchKey - Class in global

Provides a general and type-safe way to store and compare index search keys.

SearchKey(Integer) - Constructor for class global.SearchKey

Constructs a new integer search key.

SearchKey(Float) - Constructor for class global.SearchKey

Constructs a new float search key.

SearchKey(String) - Constructor for class global.SearchKey

Constructs a new string search key.

SearchKey(Object) - Constructor for class global.SearchKey

Constructs a search key from a generic value.

SearchKey(SearchKey) - Constructor for class global.SearchKey

Copy constructor for a search key.

SearchKey(byte[], short) - Constructor for class global.SearchKey

Constructs a SearchKey stored in the given data buffer.

Selection - Class in relop

The selection operator specifies which tuples to retain under a condition; in Minibase, this condition is simply a set of independent predicates logically connected by OR operators.

Selection(Iterator, Predicate...) - Constructor for class relop.Selection

Constructs a selection, given the underlying iterator and predicates.

selectRecord(RID) - Method in class heap.HeapFile

Reads a record from the file, given its id.

selectRecord(RID) - Method in class heap.HFPage

Selects a record from the page.

setAllFields(Object...) - Method in class relop.Tuple

Sets all fields, given generic values.

setCharValue(char, int, byte[]) - Static method in class global.Convert

Writes a unicode character into the given byte array at the specified position.

setCharValue(char, int) - Method in class global.Page

Sets a char at the given page offset.

setCurPage(PageId) - Method in class heap.HFPage

Sets the current page's id.

setData(byte[]) - Method in class global.Page

Set accessor for the data byte array.

setField(int, Object) - Method in class relop.Tuple

Sets a field's value generically.

setField(String, Object) - Method in class relop.Tuple

Sets a field's value generically, by column name.

setFloatFld(int, float) - Method in class relop.Tuple

Sets a float field.

setFloatValue(float, int, byte[]) - Static method in class global.Convert

Writes a float into the given byte array at the specified position.

setFloatValue(float, int) - Method in class global.Page

Sets a float at the given page offset.

setIntFld(int, int) - Method in class relop.Tuple

Sets an integer field.

setIntValue(int, int, byte[]) - Static method in class global.Convert

Writes an integer into the given byte array at the specified position.

setIntValue(int, int) - Method in class global.Page

Sets an int at the given page offset.

setNextPage(PageId) - Method in class heap.HFPage

Sets the next page's id.

setPage(Page) - Method in class global.Page

Sets this page's data array to share the given page's data array.

setPrevPage(PageId) - Method in class heap.HFPage

Sets the previous page's id.

setSchema(Schema) - Method in class relop.Iterator

setShortValue(short, int, byte[]) - Static method in class global.Convert

Writes a short into the given byte array at the specified position.

setShortValue(short, int) - Method in class global.Page

Sets a short at the given page offset.

setStringFld(int, String) - Method in class relop.Tuple

Sets a string field (automatically truncates, if necessary).

setStringValue(String, int, byte[]) - Static method in class global.Convert

Writes a string into the given byte array at the specified position.

setStringValue(String, int) - Method in class global.Page

Sets a string at the given page offset.

setType(short) - Method in class heap.HFPage

Sets the arbitrary type of the page.

The simplest of all join algorithms: nested loops (see textbook, 3rd edition, section 14.4.1, page 454).

SimpleJoin(Iterator, Iterator, Predicate...) - Constructor for class relop.SimpleJoin

Constructs a join, given the left and right iterators and join predicates (relative to the combined schema).

SLOT_SIZE - Static variable in class heap.HFPage

Size of a record slot.

slotno - Variable in class global.RID

The record's slot number.

SortKey - Class in global

One term in an ORDER BY clause; i.e.

SortKey(Object, boolean) - Constructor for class global.SortKey

Constructs a SortKey from the given values.

STRING - Static variable in class global.AttrType

SystemCatalog - Static variable in class global.Minibase
