Returns:

The iterator

Throws:

IOReturnException - if the iterator could not be retrieved.

getChildEntry

public IOKit.IORegistryEntry getChildEntry(String plane)

Convenience method for IOKit.IORegistryEntryGetChildEntry(com.sun.jna.platform.mac.IOKit.IORegistryEntry, java.lang.String, com.sun.jna.ptr.PointerByReference) to return the first child of this registry entry in a plane.

Parameters:

plane - The name of an existing registry plane.

Returns:

The child registry entry, if a child exists, null otherwise

Throws:

IOReturnException - if the entry exists but could not be retrieved.

getParentEntry

public IOKit.IORegistryEntry getParentEntry(String plane)

Convenience method for IOKit.IORegistryEntryGetParentEntry(com.sun.jna.platform.mac.IOKit.IORegistryEntry, java.lang.String, com.sun.jna.ptr.PointerByReference) to return the first parent of this registry entry in a plane.

Parameters:

plane - The name of an existing registry plane.

Returns:

The parent registry entry, if a parent exists, null otherwise

Throws:

IOReturnException - if the entry exists but could not be retrieved.

createCFProperty

public CoreFoundation.CFTypeRef createCFProperty(CoreFoundation.CFStringRef key)

Convenience method for IOKit.IORegistryEntryCreateCFProperty(com.sun.jna.platform.mac.IOKit.IORegistryEntry, com.sun.jna.platform.mac.CoreFoundation.CFStringRef, com.sun.jna.platform.mac.CoreFoundation.CFAllocatorRef, int) to create a CF representation of this registry entry's property.

Parameters:

key - A CFString specifying the property name.

Returns:

A CF container is created and returned the caller on success.

The caller should release with CoreFoundation.CFRelease(com.sun.jna.platform.mac.CoreFoundation.CFTypeRef).

createCFProperties

public CoreFoundation.CFMutableDictionaryRef createCFProperties()

Convenience method for IOKit.IORegistryEntryCreateCFProperties(com.sun.jna.platform.mac.IOKit.IORegistryEntry, com.sun.jna.ptr.PointerByReference, com.sun.jna.platform.mac.CoreFoundation.CFAllocatorRef, int) to create a CF dictionary representation of this registry entry's property table.

Returns:

The property table.

The caller should release with CoreFoundation.CFRelease(com.sun.jna.platform.mac.CoreFoundation.CFTypeRef).

Throws:

IOReturnException - if the entry could not be retrieved.

searchCFProperty

CoreFoundation.CFTypeRef searchCFProperty(String plane,
 CoreFoundation.CFStringRef key,
 int options)

Convenience method for IOKit.IORegistryEntrySearchCFProperty(com.sun.jna.platform.mac.IOKit.IORegistryEntry, java.lang.String, com.sun.jna.platform.mac.CoreFoundation.CFStringRef, com.sun.jna.platform.mac.CoreFoundation.CFAllocatorRef, int) to create a CF representation of a registry entry's property searched from this object.

Parameters:

plane - The name of an existing registry plane. Plane names are defined in IOKitKeys.h, for example, kIOServicePlane.

key - A CFString specifying the property name.

options - IOKit.kIORegistryIterateRecursively may be set to recurse automatically into the registry hierarchy. Without this option, this method degenerates into the standard IOKit.IORegistryEntryCreateCFProperty(com.sun.jna.platform.mac.IOKit.IORegistryEntry, com.sun.jna.platform.mac.CoreFoundation.CFStringRef, com.sun.jna.platform.mac.CoreFoundation.CFAllocatorRef, int) call. IOKit.kIORegistryIterateParents may be set to iterate the parents of the entry, in place of the children.

Returns:

A CF container is created and returned the caller on success. The caller should release with CFRelease.

getStringProperty

public String getStringProperty(String key)

Convenience method to get a String value from this IO Registry Entry.

Parameters:

key - The string name of the key to retrieve

Returns:

The value of the registry entry if it exists; null otherwise

getLongProperty

public Long getLongProperty(String key)

Convenience method to get a Long value from this IO Registry Entry.

Parameters:

key - The string name of the key to retrieve

Returns:

The value of the registry entry if it exists; null otherwise

This method assumes a 64-bit integer is stored and does not do type checking. If this object's type differs from the return type, and the conversion is lossy or the return value is out of range, then this method returns an approximate value.

getIntegerProperty

public Integer getIntegerProperty(String key)

Convenience method to get an Integer value from this IO Registry Entry.

Parameters:

key - The string name of the key to retrieve

Returns:

The value of the registry entry if it exists; null otherwise

This method assumes a 32-bit integer is stored and does not do type checking. If this object's type differs from the return type, and the conversion is lossy or the return value is out of range, then this method returns an approximate value.

getDoubleProperty

public Double getDoubleProperty(String key)

Convenience method to get a Double value from this IO Registry Entry.

Parameters:

key - The string name of the key to retrieve

Returns:

The value of the registry entry if it exists; null otherwise

This method assumes a floating point value is stored and does not do type checking. If this object's type differs from the return type, and the conversion is lossy or the return value is out of range, then this method returns an approximate value.

getBooleanProperty

public Boolean getBooleanProperty(String key)

Convenience method to get a Boolean value from this IO Registry Entry.
