oaViaHeader 在 oapy 中可用，可通过 _design 模块访问。

本页汇总 oaViaHeader 当前在 oapy 中可用的 Python 接口。

详细说明

The oaViaHeader class implements an object that contains information about a particular oaViaDef and all of the vias that reference it。 An oaViaHeader is an automatic object that is created and destroyed by the database。 A viaHeader may be either an oaStdViaHeader or oaCustomViaHeader and is associated with standard or custom vias, respectively。 A viaHeader is automatically created whenever the first via of a particular viaDef is created。 A viaHeader is destroyed when the last via using the viaDef is destroyed。 The oaViaHeader class can be observed by deriving from oaObserver 。 A discussion of the role oaViaHeader objects in the context of the oaVia objects they reference can be found in the Representing Vias in OpenAccess section of the Programmers Guide。

方法说明

`obj.getViaDef()`

绑定状态: 已绑定

Python 调用: obj.getViaDef()

This function returns the viaDef object associated with this viaHeader。 If the viaHeader is bound, the viaDef is returned。 Otherwise, NULL is returned。

Python 示例

from oapy._oa import _design

# assume obj is a oaViaHeader
obj.getViaDef()

`obj.getViaDefName(name)`

绑定状态: 已绑定

Python 调用: obj.getViaDefName(name)

This function returns the name of the viaDef associated with this viaHeader。

Python 示例

from oapy._oa import _design

# assume obj is a oaViaHeader
obj.getViaDefName(name)

`obj.getVias()`

绑定状态: 已绑定

Python 调用: obj.getVias()

This function returns the collection of vias associated with this viaHeader。

Python 示例

from oapy._oa import _design

# assume obj is a oaViaHeader
obj.getVias()

`obj.getSubHeaders()`

绑定状态: 已绑定

Python 调用: obj.getSubHeaders()

This function returns a collection of subHeaders in this superHeader。

Python 示例

from oapy._oa import _design

# assume obj is a oaViaHeader
obj.getSubHeaders()

`_design.oaViaHeader.find(block, viaDefName)`

绑定状态: 已绑定

Python 调用: _design.oaViaHeader.find(block, viaDefName)

This function searches the specified block for a viaHeader associated with the specified viaDef。 If the viaHeader is found, it is returned。 Otherwise, NULL is returned。

Python 示例

from oapy._oa import _design

_design.oaViaHeader.find(block, viaDefName)

`_design.oaViaHeader.find(block, viaDef)`

绑定状态: 已绑定

Python 调用: _design.oaViaHeader.find(block, viaDef)

This function searches the specified block for an viaHeader with the specified viaDef name。 If the viaHeader is found, it is returned。 Otherwise, NULL is returned。

Python 示例

from oapy._oa import _design

_design.oaViaHeader.find(block, viaDef)
