概览

oaMemoryError 在 oapy 中可用，可通过 _base 模块访问。

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

详细说明

The oaMemoryError class represents an exception that OpenAccess throws when oaMemory::get() or oaMemory::resize() is called for a process and it detects that the process is out of memory。 The class includes functions that can be used to access system and process memory information related to the out-of-memory exception。

方法说明

obj.getAllocSize()

绑定状态: 已绑定

Python 调用: obj.getAllocSize()

This function returns the size of memory that OpenAccess tried to allocate。

Python 示例

from oapy._oa import _base

# assume obj is a oaMemoryError
obj.getAllocSize()

obj.getSbrk()

绑定状态: 已绑定

Python 调用: obj.getSbrk()

This function returns the size of virtual memory on the heap。

Python 示例

from oapy._oa import _base

# assume obj is a oaMemoryError
obj.getSbrk()

obj.getOAVMSize()

绑定状态: 已绑定

Python 调用: obj.getOAVMSize()

This function returns the total number of bytes OpenAccess is currently using in virtual memory including all allocations it has made。

Python 示例

from oapy._oa import _base

# assume obj is a oaMemoryError
obj.getOAVMSize()

obj.getAvailableMem()

绑定状态: 已绑定

Python 调用: obj.getAvailableMem()

This function returns the size of available system memory。

Python 示例

from oapy._oa import _base

# assume obj is a oaMemoryError
obj.getAvailableMem()

obj.getPhysicalMem()

绑定状态: 已绑定

Python 调用: obj.getPhysicalMem()

This function returns the size of system physical memory。

Python 示例

from oapy._oa import _base

# assume obj is a oaMemoryError
obj.getPhysicalMem()

obj.getLimitMem()

绑定状态: 已绑定

Python 调用: obj.getLimitMem()

This function returns the size of the memory limit, if set。

Python 示例

from oapy._oa import _base

# assume obj is a oaMemoryError
obj.getLimitMem()

obj.isUnlimited()

绑定状态: 已绑定

Python 调用: obj.isUnlimited()

This function returns true if the memory limit is set; otherwise it returns false。

Python 示例

from oapy._oa import _base

# assume obj is a oaMemoryError
obj.isUnlimited()
