Interface WebdavCommand.IfHandler

Enclosing interface:

WebdavCommand

public static interface WebdavCommand.IfHandler

Callback handler to test the assertions made by the If header. This interface is implemented by the resource provider.

Method Summary

boolean	containsETags(java.net.URI resource, java.util.List<java.lang.String> eTags) Checks if the resource contains the ETag
boolean	containsLockTokens(java.net.URI resource, java.util.List<java.net.URI> lockTokens) Checks if the resource contains the lock tokens
void	filterResources(java.util.Set<java.net.URI> aDst, java.util.Set<java.net.URI> aSrc) Populates the destination sets with the URIs of all resources that need to be tested against the If header.

Method Detail

containsETags

boolean containsETags(java.net.URI resource,
                      java.util.List<java.lang.String> eTags)
                      throws java.io.IOException

Checks if the resource contains the ETag

Parameters:

resource - resource URI, not null

eTags - the ETags, not null nor empty

Returns:

true if all eTags are contained, else false

Throws:

java.io.IOException

containsLockTokens

boolean containsLockTokens(java.net.URI resource,
                           java.util.List<java.net.URI> lockTokens)
                           throws java.io.IOException

Checks if the resource contains the lock tokens

Parameters:

resource - resource URI, not null

lockTokens - the lock tokens, not null nor empty

Returns:

true if all lock tokens are contained, else false

Throws:

java.io.IOException

filterResources

void filterResources(java.util.Set<java.net.URI> aDst,
                     java.util.Set<java.net.URI> aSrc)
                     throws java.io.IOException

Populates the destination sets with the URIs of all resources that need to be tested against the If header. Implementors may use the source set as a starting point, this set contains all resources explicitly listed in the If header

Parameters:

aDst - target set, not null

aSrc - read-only source set, not null but may be empty

Throws:

java.io.IOException
