Class AddressKeyRecordIterator

java.lang.Object

ghidra.program.database.map.AddressKeyRecordIterator

All Implemented Interfaces:

RecordIterator

public class AddressKeyRecordIterator
extends java.lang.Object
implements RecordIterator

Returns a RecordIterator over records that are address keyed. Various constructors allow the iterator to be restricted to an address range or address set and optionally to be positioned at some starting address.

Constructor Summary

Constructors

Constructor	Description
AddressKeyRecordIterator(Table table, AddressMap addrMap)	Construcs a new AddressKeyRecordIterator that iterates over all records in ascending order.
AddressKeyRecordIterator(Table table, AddressMap addrMap, Address startAddr, boolean before)	Construcs a new AddressKeyRecordIterator that iterates over records starting at given start address.
AddressKeyRecordIterator(Table table, AddressMap addrMap, Address minAddr, Address maxAddr, Address startAddr, boolean before)	Constructs a new AddressKeyRecordIterator that iterates over records that are within an address range with an optional start address within that range.
AddressKeyRecordIterator(Table table, AddressMap addrMap, AddressSetView set, Address startAddr, boolean before)	Construcs a new AddressKeyRecordIterator that iterates over records that are contained in an address set with an optional start address within that set.

Method Summary

Modifier and Type	Method	Description
boolean	delete()	Delete the last Record read via the next or previous methods.
boolean	hasNext()	Return true if a Record is available in the forward direction.
boolean	hasPrevious()	Return true if a Record is available in the reverse direction
java.util.Iterator<DBRecord>	iterator()
DBRecord	next()	Return the nexy Record or null if one is not available.

AddressKeyRecordIterator

public AddressKeyRecordIterator(Table table,
                                AddressMap addrMap)
                         throws java.io.IOException

Construcs a new AddressKeyRecordIterator that iterates over all records in ascending order. Memory addresses encoded as Absolute are not included.

Parameters:

table - the table to iterate.

addrMap - the address map

Throws:

java.io.IOException - if a database io error occurs.

AddressKeyRecordIterator

public AddressKeyRecordIterator(Table table,
                                AddressMap addrMap,
                                Address startAddr,
                                boolean before)
                         throws java.io.IOException

Construcs a new AddressKeyRecordIterator that iterates over records starting at given start address. Memory addresses encoded as Absolute are not included.

Parameters:

table - the table to iterate.

addrMap - the address map

startAddr - the address at which to position the iterator. The iterator will be positioned either before or after the start address depending on the before parameter.

before - if true, the iterator will be positioned before the start address, otherwise it will be positioned after the start address.

Throws:

java.io.IOException - if a database io error occurs.

AddressKeyRecordIterator

public AddressKeyRecordIterator(Table table,
                                AddressMap addrMap,
                                Address minAddr,
                                Address maxAddr,
                                Address startAddr,
                                boolean before)
                         throws java.io.IOException

Constructs a new AddressKeyRecordIterator that iterates over records that are within an address range with an optional start address within that range. Memory addresses encoded as Absolute are not included.

Parameters:

table - the table to iterate.

addrMap - the address map

minAddr - the minimum address in the range.

maxAddr - tha maximum address in the range.

startAddr - the address at which to position the iterator. The iterator will be positioned either before or after the start address depending on the before parameter. If this parameter is null, then the iterator will start either before the min address or after the max address depending on the before parameter.

before - if true, the iterator will be positioned before the start address, otherwise it will be positioned after the start address. If the start address is null, then if the before parameter is true, the iterator is positioned before the min. Otherwise the iterator is positioned after the max address.

Throws:

java.io.IOException - if a database io error occurs.

AddressKeyRecordIterator

public AddressKeyRecordIterator(Table table,
                                AddressMap addrMap,
                                AddressSetView set,
                                Address startAddr,
                                boolean before)
                         throws java.io.IOException

Construcs a new AddressKeyRecordIterator that iterates over records that are contained in an address set with an optional start address within that set. Memory addresses encoded as Absolute are not included.

Parameters:

table - the table to iterate.

addrMap - the address map

set - the address set to iterate over.

startAddr - the address at which to position the iterator. The iterator will be positioned either before or after the start address depending on the before parameter. If this parameter is null, then the iterator will start either before the min address or after the max address depending on the before parameter.

before - if true, the iterator will be positioned before the start address, otherwise it will be positioned after the start address. If the start address is null, then if the before parameter is true, the iterator is positioned before the min. Otherwise the iterator is postioned after the max address.

Throws:

java.io.IOException - if a database io error occurs.
