方法

限定符和类型	方法和说明
VFSStatus	canWrite()
VFSStatus	copyFrom(VFSItem source) copy either a file or a folder to this folder. e.g. this folder is based at /bla/blu, copying source bli (from /whatever/bli) will add a child bli, so it looks like /bla/blu/bli later. the operation fails when the source or target do not support canCopyFrom and canCopyTo, resp., or there is already a child with the same name, or the quota would be exceeded.
VFSContainer	createChildContainer(java.lang.String name) Create a new child container (of same type) if possible.
VFSLeaf	createChildLeaf(java.lang.String name) Create a new leaf (of same type) if possible,
VFSStatus	delete() deletes the item. if the item is a container, all children will be deleted recursively
VFSStatus	deleteItems()
VFSItemFilter	getDefaultItemFilter()
java.util.List<VFSItem>	getItems()
java.util.List<VFSItem>	getItems(VFSItemFilter filter)
VFSStatus	rename(java.lang.String newname)
VFSItem	resolve(java.lang.String path) a relative path. the implementation will search all its children. e.g. bla/blu/bli.txt this vfsitem's name must thus be 'bla'
void	setDefaultItemFilter(VFSItemFilter defaultFilter) Set a default filter that will be applied to this container getItems method
java.lang.String	toString()

构造器详细资料

LocalFolderImpl

public LocalFolderImpl(java.io.File folderFile)

Constructor

参数:

folderFile - The real file of type directory wrapped by this VFSContainer

方法详细资料

getItems

public java.util.List<VFSItem> getItems()

指定者:

getItems 在接口中 VFSContainer

返回:

a list of VFSItem containing

getItems

public java.util.List<VFSItem> getItems(VFSItemFilter filter)

指定者:

getItems 在接口中 VFSContainer

返回:

a list of VFSItem which are accepted by the given filter. If a default filter is set, the default filter will be applied in addition to the given filter in this method

setDefaultItemFilter

public void setDefaultItemFilter(VFSItemFilter defaultFilter)

从接口复制的说明: VFSContainer

Set a default filter that will be applied to this container getItems method

指定者:

setDefaultItemFilter 在接口中 VFSContainer

copyFrom

public VFSStatus copyFrom(VFSItem source)

从接口复制的说明: VFSContainer

copy either a file or a folder to this folder. e.g. this folder is based at /bla/blu, copying source bli (from /whatever/bli) will add a child bli, so it looks like /bla/blu/bli later. the operation fails when the source or target do not support canCopyFrom and canCopyTo, resp., or there is already a child with the same name, or the quota would be exceeded.

指定者:

copyFrom 在接口中 VFSContainer

参数:

source - the source (must exist)

返回:

the status

canWrite

public VFSStatus canWrite()

指定者:

canWrite 在接口中 VFSItem

覆盖:

canWrite 在类中 LocalImpl

返回:

true if a child can be added at all(only files and folder cab be copied to). the operation may still fail because e.g. of quota limitation.

rename

public VFSStatus rename(java.lang.String newname)

指定者:

rename 在接口中 VFSItem

指定者:

rename 在类中 LocalImpl

参数:

newname - e.g test.txt or myfolder (no path prepended)

返回:

status

delete

public VFSStatus delete()

从接口复制的说明: VFSItem

deletes the item. if the item is a container, all children will be deleted recursively

指定者:

delete 在接口中 VFSItem

指定者:

delete 在类中 LocalImpl

返回:

status

resolve

public VFSItem resolve(java.lang.String path)

从接口复制的说明: VFSItem

a relative path. the implementation will search all its children. e.g. bla/blu/bli.txt this vfsitem's name must thus be 'bla'

指定者:

resolve 在接口中 VFSItem

返回:

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object

createChildContainer

public VFSContainer createChildContainer(java.lang.String name)

从接口复制的说明: VFSContainer

Create a new child container (of same type) if possible.

指定者:

createChildContainer 在接口中 VFSContainer

返回:

VFSItem if successfull, null otherwise.

createChildLeaf

public VFSLeaf createChildLeaf(java.lang.String name)

从接口复制的说明: VFSContainer

Create a new leaf (of same type) if possible,

指定者:

createChildLeaf 在接口中 VFSContainer

返回:

VFSItem if successfull, null otherwise.

getDefaultItemFilter

public VFSItemFilter getDefaultItemFilter()

指定者:

getDefaultItemFilter 在接口中 VFSContainer

返回:

The default filter for this container or NULL if no filter is set

deleteItems

public VFSStatus deleteItems()

指定者:

deleteItems 在接口中 VFSContainer
