pymel.core.system.dbpeek¶
- dbpeek(*args, **kwargs)¶
The dbpeekcommand is used to analyze the Maya data for information of interest. See a description of the flags for details on what types of things can be analyzed.
Flags:
Long Name / Short Name Argument Types Properties allObjects / all bool Ignore any specified or selected objects and peek into all applicable objects. The definition of allObjectswill vary based on the peek operation being performed - see the flag documentation for details on what it means for a given operation. By default if no objects are selected or specified then it will behave as though this flag were set. argument / a unicode Specify one or more arguments to be passed to the operation. The acceptable values for the argument string are documented in the flag to which they will be applied. If the argument itself takes a value then the value will be of the form argname=argvalue. count / c int Specify a count to be used by the test. Different tests make different use of the count, query the operation to find out how it interprets the value. For example a performance test might use it as the number of iterations to run in the test, an output operation might use it to limit the amount of output it produces. evaluationGraph / eg bool Ignore any nodes that are not explicitly part of the evaluation graph. Usually this means nodes that are affected either directly or indirectly by animation. May also tailor the operation to be EM-specific in the areas where the structure of the DG differs from the structure of the EM, for example, plug configurations. This is a filter on the currently selected nodes, including the use of the allObjectsflag. operation / op unicode Specify the peeking operation to perform. The various operations are registered at run time and can be listed by querying this flag without a value. If you query it with a value then you get the detail values that peek operation accepts and a description of what it does. In query mode, this flag can accept a value. outputFile / of unicode Specify the location of a file to which the information is to be dumped. Default will return the value from the command. Use the special names stdoutand stderrto redirect to your command window. The special name msdevis available when debugging on Windows to direct your output to the debug tab in the output window of Visual Studio. Flag can have multiple arguments, passed either as a tuple or a list. Derived from mel command maya.cmds.dbpeek
Example:
import pymel.core as pm import maya.cmds as cmds // Find the available peek operations pm.dbpeek( op=True, query=True ) # Return: ['metadata', 'nodes', 'references', 'plugIterator'] # // Describe the detail of a single available type pm.dbpeek( query=True, op='nodes' ) # Return: 'The operation 'nodes' understands type flags 'attributes, visible'. The 'visible' flag filters the display list to ignore any hidden or internal nodes. Default is to show all nodes Normal display will show a count of nodes in the scene of each type. Adding the 'attributes' flag includes the attribute count for each node as well, segregated by static, extension, and dynamic types. '# # Describe the detail of a single available operation pm.dbpeek( query=True, op='plugIterator' ) # Return: 'The test 'plugIterator' doesn't have any type flags. Suggested iteration count minimum is 1000000 for which the test machine measured a time of 19.234s. This tests the performance of the class which iterates over all of the networked plugs in a plug tree. '# pm.dbpeek( op='plugIterator', count=10000 ) # Return: 'Run 10,000 loops of plug iteration over a tree of size 51, depth 4 Total time: 17.0s Maximum time: 0.81s Minimum time: 0.23s Average time: 0.30s '# # Run a performance test for 1000000 loops and store the results pm.dbpeek( op='plugIterator', count=1000000, outputFile='MyFile.txt' ) # Return: 0 # pm.loadPlugin( 'MetadataSample' ) pm.polyPlane( name='planeLuck' ) pm.dataStructure( asString='name=TestStructure:int32=ID ) pm.importMetadata( asString='channel face\n stream\n TestStream\n TestStructure\n 0\n 99\n 1\n 999\n 2\n 9999\n endStream\n endChannel\n endAssociations" "planeLuckShape' ) # Peek at the newly created metadata # pm.dbpeek( op='metadata', type='summary' ) # Return: 'Node planeLuckShape : face( TestStream[3] )' #
